Application filed Kay 23, 1921.

To aZZ whom ii may concern:

Be it known that l, Hose Moon, a citizen of the United States, residing at 930 St. Nicholas Avenue, in the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Heat Insulators, of which the following is a specification.

l his invention relates to heat insulators and has for its object the provision of a heat insulator which will be economical and eilicient.

The principal object of the invention is the employment of ordinary powdered sulphur as a heat insulator in a form iii-which it will be convenient to use and adaptable for various conditions.

It is well known that ordinary powdered sulphur is an excellent non-conductor of heat, but as a powder it is inconvenient to use on account of its tendency to pack 'or agglomerate and there are objections against the use of any heat insulator in powdered form. I obviate these defects by forming the sulphur by means of pressure or an adhesive into a brick and coating the outside of the brick'with a plastic mass so that the brick will permanently retain its shape and can be used for lining walls,'etc., as a heat insulator.

In the drawing, Figure 1 shows a perspective partly in section, of the improved heat non-conducting brick. Figure 2 shows a. section of the brick along the lines 2-2 of Figure 1, A representing the sulphur interior of the brick and B the plastic lining.

The brick is made in the following manner:-

- A quantity of powdered sulphur is taken and compressed with a small amount of pressure into the form of bricks shown as A in.

certain porosity in the sulphur brick itselfi,

tierial its.

is properly briquetted, the bricks co on all sides thereof with T; coating may be accomplished by rapidly dipping the bricks into the. melted asphaltum and removing same immediately from said melted asphaltum so that only a thin layer of said asphaltum remains on the outside of the brick, care being taken that the sulphur brick is not exposed for a long time 66 to the action of the heated asphaltum. Gih sonite or a similar product, of course, may be substituted for the asphaltum.

The bricks can also be painted with an asphaltum or rubber solution successively on the six sides thereof, and after the first coating is dry, a heavier coating may be applied by further painting or saturation in a solution of asphaltum or in melted asphaltum. If desired to increase the strength 70 of the asphaltum coating, lam black or a similar powder may be adde to the asphaltum. y

In this way a coated brick is obtained which is transportable and which may be easily joined to other bricks of a similar nature to form insulating walls.-

-I prefer asphaltum or'rubber as the cover ing for this sulphur brick as there is a certaln afiinity between asphaltum or rubber and sulphur and it is possible by careful manipulation to partially vulcanize the layer of coating to the sulphur interior.

What I claim is 1. An insulating brick having a core of sulphur and an external layer of asphaltum.

2. An insulating brick having a core of powdered sulphur and an external layer of asphaltum.

3. An insulating brick having the interior ac thereof composed of powdered sulphur and a relatively thin outer covering of asphaltum.

4. An insulating brick having the interior thereof composed of powdered sulphur and a relatively thin covering of a flexible. and a5 adherent material.

5. An insulating brick having the interior thereof composed of sulphur with an outer coating of vulcanizable material In testimony whereof I hereunto afix my me a signature.
